Public bug reported:
I launch QEMU with the following command line:
qemu-system-i386 /home/ruslan/iso/Windoze/qemuxp.img -m 512 -display sdl
-vga vmware -enable-kvm
The guest OS is Windows XP. To reproduce the problem, do this:
0. Make sure guest is WinXP (don't know if it's really necessary), use vmware VGA
1. Set mouse cursor theme to default black&white theme, i.e. that without any translucency etc.
2. Open a text editor, e.g. built-in notepad
3. Move the cursor inside text entry widget
4. See the cursor jumping away. You basically can't enter the cursor there.
This also reproduces with MS Word 2003 even with oxy-white cursor theme
(i.e. that with translucency) — seems Word uses its plain
black&transparent cursor for I-beam cursor.
This doesn't happen with other VGAs, i.e. cirrus and std.
I used qemu git master to test this. qemu-system-i386 --version reports
version 2.0.90, git describe says v2.1.0-rc0-1-g9d9de25. This also
happened in earlier QEMU versions, like 1.5.x and older.

I've checked with Kubuntu 14.04 LiveCD as guest, and there's no such problem.
What seems relevant is that in Kubuntu mouse cursor seamlessly enters and exits the window, i.e. mouse is automatically grabbed and ungrabbed, while on WinXP guest it's not supported (I think I just didn't install such a driver). Maybe it's this mode which makes behavior different.

After some experimenting it starts to seem that this is a special case
of a more general problem with HW accelerated cursor. This particular
bug can be reproduced without any edit field — it's enough to try moving
the classical cursor (i.e. HW accelerated as set in 1. in bug
description) over some window edges so that it changes its shape to
resize arrows and back to usual pointer.
Now, it appears that if I set mouse cursor speed to smallest possible,
then the cursor moves _very_ jittery. It is close to unusable.
This may indicate some principal problem with such implementation of HW
accelerated cursor. What if instead of using the real system cursor QEMU
would create a (undecorated) window which would be the guest cursor,
still rendered with some HW acceleration? In this case it'd be not
necessary to always have the real cursor near the guest cursor, in fact
the video driver won't even touch the real cursor at all.

Setting SDL_VIDEO_X11_DGAMOUSE=0 environment variable works around this
problem.

Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? Or could we close this ticket nowadays?

This is an automated cleanup. This bug report has been moved to QEMU's
